RADIATOR

A6E363015200T01

Structure

•

A cross-flow radiator with corrugated fins is used for improved cooling.

•

The radiator tanks are made of plastic and the core is made of aluminum.

•

Four rubber-insulated mounting brackets are utilized to decrease vibration.

•

The radiator has an ATF cooler in the radiator tank. (ATX)

•

A small pressuring type cap has been adopted for
the radiator cap.

COOLING FAN

A6E363015140T01

Structure

•

Electric cooling fans No.1 and No.2, operated according to a fan control signal from the PCM, have been
adopted. Due to this, engine noise is reduced and rapid warming-up is possible.

•

A cooling fan No.1 and No.2 is attached to the radiator cowling.

COOLING SYSTEM

RADIATOR COWLING, COOLANT RESERVOIR TANK

A6E363015140T02

Structure

•

A radiator cowling is made of plastic for the weight reduction.

•

A coolant reservoir tank can be removed from the radiator cowling. (For Israel and L3 engine models)

•

A coolant reservoir tank can not be removed from the radiator cowling. (LF engine models except for Israel and
L8 engine models)

THERMOSTAT

A6E363015171T01

Structure

•

A wax-type thermostat with a jiggle-pin has been adopted.

•

The plastic thermostat case has a built-in stainless steel thermostat body with excellent corrosion resistance.

•

When the engine coolant temperature is below 75.0

°

C {167

°

F}, the thermostat stops the circulation of radiator

coolant from the radiator for improved engine warming. When the engine coolant temperature is between
80.0

°

C {176

°

F} to 84.0

°

C {183.2

°

F}, the thermostat begins opening the valve and engine coolant flows from

the radiator to stabilize engine coolant temperature.
